MYSQL :: Selecting The Latest Date Entry

Latest Date Entry + Future Date
My requirement is data to be added to database depending on dates. Like If the user wants to add data for the next 10 days,the data should be added with a corresponding column containing the next 10 days' dates.

Then if he logs in tomorrow and wishes to add data for another 100 days,it should find the last date added and then add data with the next 100 dates starting from that date.

Also I would want to display these dates to the user.So can you suggest which type to be used for database field and also the date functions(mysql as well as php) to be achieved.

Let me put it more clearly.

"select the last date(which might be future dates) entered in the database";

If the date is Oct10 and the user wants to add entries for Oct 11,12 13

"insert into table values('data','oct11')"
......
......
likewise for Oct12 and 13

The format I need is just year,month and day.No time is required.

Selecting A Entry Within A Date Range
I have a MySQL database with 5 columns called Name, Model, Colour, Date_From, Date_To.
Basically I want the user to specify the name and a date and want it to return the corresponding entry whose matches the name and within Date_From and Date_To.

I wanted to use the date format dd-mm-yy so ive used VARCHAR. This is what ive done of which the date range doesnt work.

SELECT Name, Model, Colour, Date, Date_From, Date_To FROM Cars WHERE Name='$Name' AND '$Date BETWEEN Date_To AND Date_From'

Sorting Column1 By Latest Entry
SELECT time,referer FROM site_stats GROUP BY referer ORDER BY time DESC

this worked, however referer that comes first is at the bottom of the table although the referer entry is latest.. only refererer that havent been listed yet are on the top .. so what happens is now that it shows referer according to its latest existance ...
how can i do it so that the latest referer is ontop according to the latest time. .. which mean which ever referer that comes in by latest its group will be on top of the list ..

Selecting Latest Posts With Titles
I saw this on the big bad thread of MySQL Best Practices. It is precisely the problem I've got, but doesn't offer any answers.

select f.name
, max(dateposted)
, fp.title
from forum f
join forumpost fp
on fp.forum_id = f.forum_id
group
by f.name

Quote:

the user who wrote this query mistakenly assumes that fp.title will contain the title of the latest post from that forum. it will not. according to the mysql manual, "The server is free to return any value from the group, so the results are indeterminate unless all values are the same".

Latest Date
Multiple records with different dates, how i can only select the latest date?
This is from an archive
So i want to select the manufacturercode and the supppier with the latest date, so could have 500 manufacturer codes each with 10 entrys id'd by date i only want the latest date for each manufacturer code.

Latest Date
im new to mysql and i was programming some stuff in my website and i find that whenever i delete a row of data .. the next data that i insert will not be at the back of the table .. it will be inserted in the slot of the data that i already deleted it ..
how can i make the newest inserted data be at the back of the table ?

How To Retrieve Latest Date
I have a table that looks something like this:

table prop1 {
id;
addr;
zip;
name;
} (it's much larger than this)

And another table that looks like

table prop2 {
id;
price;
date;
}

The first table will have one entry per address. The second can have any number of entries with varying prices and dates. I need to retrieve the highest price with the latest date from prop2 for each entry in prop1.

I have tried this code:
select (p.id, p.addr, pp.id, pp.price, pp.date, MAX(pp.price) from prop1 p, prop2 pp where p.id = pp.id group by p.id order by p.addr);

This sort of does what I want. But it lists all of the results. So if one address has ten entries, all ten entries are returned. If I add a LIMIT 1, that works for the first address but no others are returned.

Is there a way to return just one entry for each address and have that entry be the one with the highest price and most recent date (or even just the highest price if need be)?

Latest Date Using 3 Tables
I am trying to join 3 tables with one table returning the latest date. Below is what I've tried. I need to display the current Rank from the record that latest date is from. What I'm getting is the latest date and the first rank (these are not the same record by the way).

What am I doing wrong? Can anyone help me? BTW, I'm using MySQL 5.0

SELECT Personnel.ID, Personnel.LastName, Personnel.FirstName, Ranks.Rank, Ranks.rankID, Promotions.DateOfRank
FROM Ranks
RIGHT JOIN (Personnel
LEFT JOIN (SELECT Promotions.MemberID, Promotions.RankID, MAX(DateOfRank) AS DateOfRank
FROM Promotions
GROUP BY MemberID) Promotions
ON Personnel.ID = Promotions.MemberID)
ON Ranks.rankID = Promotions.RankID
order by LastName, FirstName.

Latest-date Query
I am trying to get all records that share the most recent "RatesUpdated" datetime value from 1 table. I am doing the below query and I keep getting the following syntax error: "#1111 - Invalid use of group function"
SELECT t1.Product, max(t2.RatesUpdated) FROM `lqdp_mortgage_rates` t1, `lqdp_mortgage_rates` t2
WHERE t1.RatesUpdated = max(t2.RatesUpdated)
group by max(t2.RatesUpdated)

Latest Date Inserted
i have a table 'NEWS' contains a date field that takes CURDATE() when any row inserted in it.and from another php page, i want to get 1 row with the latest date in this table, i.e. the last news row inserted.what should be the SQL query?

Find Out The Date Of The Latest Sunday
Today is 26 December 2006, I want to find out what is the date of the latest sunday that passed by...the date of latest sunday given any day..

what function is used? how to find out?

Selecting Last Entry
All I need some help i have been trying to write this program for a friend that owns a internet cafe. The DB he uses is in sql he wants people to be able to see their time on his website i almost have it all written except for one problem when it selects there time it brings up all the changes to their account as in if he bought a hour yesterday it would so it i want it to show the current or last entry in the columns heres the code

SELECT userid, username, usertime, datetime
FROM users a, log b
where username = 'Their UserName'
order by datetime;

Is there any command so it shows only the last entry?

Sorting By Latest Date Field In Each Record
I have a MySQL table with the following fields:

ID (int 11) (PK)
Company (varchar 50)
Contactdate (date)
Formdate (date)
Signdate (date)

I would like make a select query that orders the records by the most
recent date (i.e. descending) of any of the three date fields and then
by company name. Some date fields may be empty (null) A record must not
be listed more once.

For example, if I have the following data:

ID, Company, Contactdate, Formdate, Signdate
1, acme1, 2006-01-01, 2006-01-10, Null
2, acme2, 2006-01-01, 2006-01-11, 2006-01-12
3, acme3, 2006-01-08, 2006-01-09, 2006-01-09

The result should be:

2, acme2
1, acme1
3, acme3

In other words, the query should determine the 'latest date
field activity' of each record and then order by that date (and then by company).

If it is complicated to use null values I can also set the default
value of the date fields to something like '1900-01-01'.

Displaying The Latest Date On A Group By Query Instead Of The 1st
I have a select statement that retrieves customer activity. What I want the result to display is each active company in a specified timeframe.

Currently when I do a group by on the result (so that it only shows each company once) the date value has the 1st login instead of the most recent...

Here is the statement so far.....

Selecting A Random Entry.
Is there any way to select a random entry?

to fit in with this statement...

SELECT * FROM `table` WHERE `type` = '1' LIMIT 1

Auto Date Entry
Is there a way to have a date automatically entered into a form, so the user does not always have to add it manually? What table Type do I use? I see a TIMESTAMP, but no DATESTAMP.

MYSQL Date Entry Shows 0000-00-00
i want the user to type in the date. Everything works fine and the form submits. When i open the database and query the results, the date field shows only 0000-00-00. It doesn't show the date entered (ex 05/23/07). What am i doing wrong?

I'm thinking it has to do something with converting the string to a date? If so, how do i do that in PHP.

Selecting By Date
I'm trying to do a very simple thing: I have in my DB a row called at_date, in it I enter a 10 digits number of date, like: 1171869716.

How can I select all the data from the table where the month is the current month (and year of course), or any month I choose?
Better saving the dates in a different format?

Selecting By Date
I have a table like this:

CREATE TABLE foo (
MyID INT NOT NULL AUTO_INCREMENT,
MyDate DATE NOT NULL,
PRIMARY KEY(MyID)
)

How can I select entries/rows of the above table which have MyDate closest to the current date? I.e. 2 rows which have MyDate set to '2004-7-15' and '2004-3-20'. The 1st row must be selected 'cos it's closer to the current date (2004-9-8).

Selecting By Date
I am setting up a transaction reporting system and am developing a page which lists the past user transactions.

What i want to be able to do is set it so that I can view all the transactions from yesterday, the last week, the last month and the last year...

is there an easy way of doing this

I have set it so i can view all transactions from the day by using

(Select * from transactions where trans_date = NOW())

is there a way to do the oyher 4 examples like this method??

Selecting By Date...Whats Better?
For example you want to select blog posts from a table by year (2007) or combination year and month (2007-02). Whats better where-clausing the date column with ....

Selecting A List Of Date
Is there any way to select a list of date by specifying the from date and the to date.
Such as:

From Date : 01-01-2005
To Date : 05-01-2005

Results
-----------
01-01-2005
02-01-2005
03-01-2005
04-01-2005
05-01-2005 .

Selecting Date Records
What is the most efficient way to select records based on a field called NOW
which contains a date or a datetimestamp

I use:
SELECT * FROM `TBL` WHERE
DATE_ADD( `TBL`.`NOW` , INTERVAL 3 MONTH ) > CURDATE( );

Is this the best way?

TIA

Selecting Date Ranges
I have many files dating back 15 years. I want to be able to display the records by the following different cases:

- Select all from current week
- Select all from current month
- Select all from past 12 weeks
- Select all from past 12 months
- Select all from specified week
- Select all form specified month
- Select all from records (i got this one down)

All the records are in the database and the dates are in DATETIME format yyyy-mm-dd.

Selecting A Date Range Using CURDATE()
When a user selects a page with the recordset I want it to list dates that
fall into a certain range, related to CURDATE(). The range fields are
start_date and end_date, which are both DATETIME column types.

Using BETWEEN won't work because it won't list a date that starts BEFORE
CURDATE() e.g.

If CURDATE() is 2005-08-10

Then an event that has a start_date of 2005-08-06 and an end_date of
2005-08-26 won't show in the list, even though the date range does fall into
the CURDATE() of 2005-08-10.

Selecting A Single Record According To Date
I have this SQL statement;

"SELECT * FROM event ORDER BY month ASC, date ASC";

But i'd only like to select the next one event in order of the date field. Instead of selecting them all. How can i order by the current date? The date and month are seperate fields.

Selecting Certain Dates From Date Column
I wonder how this can be done, data is like this

+---------------------+
| whenstamp |
+---------------------+
| 2005-02-21 12:27:54 |
| 2005-02-21 12:27:54 |
| 2005-02-21 12:27:55 |
| 2005-02-21 12:42:55 |
+---------------------+
4 rows in set (0.00 sec)

mysql>

I tried something like this ::
$this_month = mysqli_query($dbcon,"select date_format(whenstamp,'%d-%m-%Y') as datex from logs
where %m = '02'");

Basically I want to retrive records corresponding to the current month, I know I have hardcore '02' in their but that was just for testing and getting started.

Selecting Events Based On Various Date Criterias
I'm a little stuck at how to tackle this one efficiently. I'll try to explain concisely...
I have a form to search for events. Form fields include
Postcode
Event name
Venue name
When (radios)
-> today
-> tomorrow
-> this weekend
OR instead of 'When' they can choose a specific date.

In the events table there are a various columns including startdate (of type datetime). There is also a column for each day of the week that the event is repeated. For example, if the event is repeated on a monday then the column 'repeat_mo will' have a value of 1.

My difficulty lies in creating a query to retrieve all the relevant results. For example, a search could include the following variables from the form:

postcode -> YO14 7LX
when -> tomorrow

So I'd need to go to the events table and retrieve all rows that have a similar postcode, a start date that is tomorrow OR has been flagged as being repeated every wednesday.

The postcode bit is fine and getting tomorrow date (with php) is fine. But how do I put it all together to also take into account the repeat day flags?

Selecting The Highest Valued Date/time For A Particular Day
I'm new to MySQL and I am having a problem selecting the highest
valued date/time for a particular day. Here is the table structure:

Selecting A Date But Adding One Year To Result
I want to select some dates from the database but add one year to the result.

The tuple is called "TestDate" and i want to return it as DueDate in the results.

something like:

SELECT DATE_ADD('TestDate', INTERVAL 1 YEAR) AS 'Due_Date';

Selecting Date When Stored In Traditional String Format
i'm wondering why this won't work

PHP

SELECT userid, username, birthday
FROM user
WHERE SUBSTRING(birthday, 5) >= ཇ-13' AND SUBSTRING(birthday, 5) < ཇ-20'
ORDER BY birthday

i can get this to work

PHP

SELECT userid, username, birthday
FROM user
WHERE SUBSTRING(birthday, 5) >= ཇ-13'
ORDER BY birthday

and this one

PHP

SELECT userid, username, birthday
FROM user
WHERE SUBSTRING(birthday, 5) < ཇ-20'
ORDER BY birthday

but i when i try and combine them, the query fails to return any data,

Selecting Date Time Field, Difference In Minutes
I wonder if is there any way to select from a table all the records
which has a Date Field that is at least five minutes old?

In other words, I have a table with a date field and I need to select
all the records that are older than five minutes, has their date field
updated before five minutes.

Usually I do it with days by using the to_days() function and comparing
the date to now: (to_dayss(now()) - to_days(somedate)).

How Do You Enter An Entry With A Newline Inside The Entry?
I'm trying to enter an entry into the table. However, my entries must have newlines inside each entry. Further more, i'm trying to do this from an excel file(ie. first by saving it to a text file and then using LOAD DATA INFILE..).

Automatically Record Date Of Record Entry
I have my database table set up and I have an HTML form that is PHP driven that will add the information entered into the form into to my database table.

I have a local buy-sell-trade Website. The way it has worked is that people fill out a form and the results emailed to me. I then take the information and enter it into a Web page. I only want the ads to be displayed for 30 days. I keep the ad for a total of 6 weeks (displays for 30 days and sits in limbo for 2 weeks afterwords) and if not renewed within that 2 week limbo period - I delete it.

Entering all the ads and keeping up with the dates manually has become a burden. I've only recently began looking into databases. My hosting company provides me with phpmyadmin and mysql 5.0. I'm new to all of this but I have managed to set up a database table and a HTML form that is PHP driven that allows ads to be automatically added to the database table.

There is a lot I need to do to make this ideal, but one step at a time.

First, I need to know the date (March 02, 2006) the ad was created or added to the database table. I know that I need to add some piece of code to my php form to record this information, but what code and where do I put it? I know I will need to create an extra field in my database table to house the date - I can handle this.

I've read the date and time information here http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html

but there's a lot there and I don't know which is right for my needs. Plus, it doesn't tell me how or where to insert it into my php form (or does it?).

Latest Changes To A Row
Is there an easy way to get the time a row was modified last? I need it for a community-system where I want to get the time(-stamp) a user made the last changes to his profile without always update some `last_modified`-column every time he changes something.

Latest MySql5.0
i installed Mysql5.0.12 and 5.0.20, neither of which allowed the addition of a new user. Said no can save...user may have been deleted system is windows2003 server X86

Latest Enteries
I have a database made by a programmer on my site which has enteries for different diecast models in it. It is backended via a mySQL database, and uses php for the pages. It has a basic search function in it, however I am wondering if the following is possible.Is there a way that I could have one page that has the newest... say 20 enteries in it? How would I do this?

Join/Group By On Latest Row
I have a database with 2 tables, the first one is for items, and the second is a status.
I want 1 query that just returns the item with the latest status, without using a subquery (older mysql version ). Is this possible?

Example tables:

CREATE TABLE `item` (
`id` int(11) NOT NULL auto_increment,
`description` varchar(20) NOT NULL default '',
PRIMARY KEY (`id`)
) TYPE=MyISAM AUTO_INCREMENT=3 ;

INSERT INTO `item` VALUES (1, 'First');
INSERT INTO `item` VALUES (2, 'Second');

CREATE TABLE `status` (
`id` int(11) NOT NULL auto_increment,
`value` varchar(50) NOT NULL default '',
`item` int(11) NOT NULL default Ɔ',
PRIMARY KEY (`id`)
) TYPE=MyISAM AUTO_INCREMENT=5 ;

INSERT INTO `status` VALUES (1, 'First - First', 1);
INSERT INTO `status` VALUES (2, 'First - Second', 1);
INSERT INTO `status` VALUES (3, 'Second - ZFirst', 2);
INSERT INTO `status` VALUES (4, 'Second - Second', 2);

SELECT description, MAX(value)
FROM item AS i
INNER JOIN status AS s ON s.item = i.id
GROUP BY description

==>

-------------------------------
|[description] | [MAX(value)] |
===============================
|First First | Second |
-------------------------------
|Second Second | ZFirst |
-------------------------------
Gives the max value, but string based. I would like to get the value that goes with the MAX(id) of the status

Revert To Latest Records
I have about 6 months of experience with PHP and MySQL, but I'm new to the forums. I need a kind of rigged up SELECT ... WHERE statement.

SELECT * FROM splits WHERE month='6' AND year='2007'

I need it to select the latest records if no records exist for the desired month and year. I don't want to do a separate SELECT and just use mysql_numrows.

Latest In Mysql Query?
I want to run a query, to export the 10 most recent rows. There are a few possible ways i can think of to do this. I have an id column that is autoincrement, so i think i could order them in desc, then limit to 10...would it work?

Or i also have a date column, so i guess with a little more work i could list by date. Any idea how to do this?

Getting The Latest Data From A Table
I have a table that has a date colum in it (colum is 'cheatdate'). So, I was woundering how I would use a MySQL query to get the latest 10 entrys (10 more recent dates). Can someone explain how I would do that?

MySQL 5 Is Latest Version
The lastest full production release of MySQL is version 5.

Some hosts do not support version 5 yet but most should be supporting version 4.1.

If your version is older than 4.1 please note that in any new threads you start. This is because older versions do not support things like GROUP_CONCAT and subqueries among other things.

If you happen to still be on MySQL 3.x then you won't even have the ability to use UNION.

If you note that you are using an older version, then when someone is composing a solution to help you, they will give you a version that you can use on your particular release of MySQL.

Subqueries can be re-written as joins and in place of a UNION you may create a temporary table and then query results from it for instance.

Get The Latest Changed Records
I hava a table with the following information

CREATE TABLE TEMP1 (REFID INT, REVISION INT, FIELDNAM VARCHAR(10), VALUE VARCHAR(10));
INSERT INTO TEMP1 VALUES(1001, 0, A, A2);
INSERT INTO TEMP1 VALUES(1001, 0, C, C2);
INSERT INTO TEMP1 VALUES(1001, 0, E, E2);
INSERT INTO TEMP1 VALUES(1002, 0, A, A3);
INSERT INTO TEMP1 VALUES(1002, 0, B, B2);
INSERT INTO TEMP1 VALUES(1002, 0, E, E3);
INSERT INTO TEMP1 VALUES(1001, 1, A, A4);
INSERT INTO TEMP1 VALUES(1001, 1, E, E4);

Here based on latest revision and refid I should get the fieldnam and value.
Expected output:
REFID FIELDNAM VALUE REVISION
1001 A A4 1
1001 E E4 1
1002 B B2 0
1001 C C2 0

Query For Displaying Results Except Latest
So I'm looking for a way to pull the results from the database showing all the records EXCEPT for the latest one i.e. if there are 30 recordsets I only want to show numbers 1-29.

How To Find The Latest Record In MySQL?
Probably a really simple answer, but I have no idea on what to do...

Basically I am displaying my table fine, but I would like to only display the last inserted record. So say the last insertion was id number 79, that's all I want to display?

Asking The Latest Added Lines From MySQL
How do i ask the latest added information in a table from MySQL, and display it? I want this to display the latest topics on my forums. And let it display the latest articles and scripts.

Latest MySQL Version With Fedora Core 1
I currently have a server running Fedora Core 1. I ran the "yum update" command a couple of minutes ago to upgrade all files from the repository, and it didn't upgrade my MySQL installation (3.23). I checked the repository and that was the latest version it had.

My question is: can I install the latest MySQL version (with RPM, uninstalling the 3.23 package first) on my current version of Fedora, or will I have installation or performance/stability issues?

Delete Except Latest 2500 Entries (was "help With Query")
I have a table that holds information on activities.
For each activity I store the following:
ID, When, Description
The ID is the key for the table
The When column holds the datetime when the activity was added

The table gets filled up pretty quickly.
I would like to run a query that will delete ALL the entries except for the 2500 latest ones. The When column should be the one to use when deciding which are the 2500 latest activities

Can someone show me the most efficient way of doing this?
